JNIARTEN ANDERSON, OF TURLOGK, CALIFORNIA.

COW STANCI-IION.

Application filed May 20, 1924;. Serial No. 714,702.

To all whom it may concern:

Be it known that I, MARTIN ANDnnsoN, a citizen of the United States, residing at Turlock, in the county of Stanislaus and State of California, have invented new and useful improvements in Cow Stanchions, of which the following is a specification;

This invention relates to improvements in cow stanchions and has particular reference to means for opening or closing the stanchion collectively or individually.

The principal object of this invention is to provide means whereby all of the cattle may be released or locked in simultaneously and from a remote point or, if necessity de mands, one animal may be released or retained, while the remainder are released.

Another object is to produce a device of this character which is simple in construction, neat in appearance, sanitary and well within the purchase price of the average user.

A still further object is to produce a device of this character which may be easily installed in any standard type of barn, and one which will lend itself to installation with standard equipment.

Other objects and advantages will be ap parent during the course of the following description.

In the accompanying drawings forming a part of this s1 ecification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of my device,

Figure 2 is a top plan view thereof,

Figure 3 is a cross section taken on the line 3-3 of Figure 1, and

Figure 1 is a detail view of the operating lever.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a pipe extending across the barn at the head end of the stalls. Secured upon this pipe, at intervals, are clamps 6 which serve to position a sheavecarrying block 7 and a yoke-securing block 8. The sheave carrying block 6 has mounted thereon sheaves 9 and 10. The sheave 9 hasa cable 11 reave-d thereover, which cable is attached to a pin 12 secured Within a latch box 13, which box is, in turn, secured to longitudinal members 1 L mounted within the pipe 5. i

A slot 16 permits the pin 12 to be reciprocated as willbe later shown. The sheave 10 has a cable 17 reaved thereover, one end of which cable is secured to a pin 13 passing through a slot in the pipe 5 and secured in one of the longitudinal members 14-. The opposite end of the cables 11 and 17 are carded to a distant point and secured to a drum 19 which is actuated by a lever 21 and held against accidental movement by a ("log 22 engaging a quadrant 23. I

A latch mechanism 24 serves to optto the dog 22 through the medium of a link 26. Secured to the block 8 is a downwardly extending lug 27 to which one end of a yoke member 28 is secured. The opposits end of this yoke member is, in turn, secured to a block 29 mounted upon the floor of the stall.

A similar yoke member 31 is pivoted to the block and has its opposite end secured to a latch box 32 having a sliding bolt 33 mounted therein. This sliding bolt is adapt-- ed to be normally held in its full'line position of Figure 3 by a spring 34: and to be retracted by an operating pin 36 extending through a slot 37 the free end of which bolt passes through a slot 38 in the bottom of the pipe 5 and enters the latch block 13.

A chain 39 has its opposite ends connected to the lug 27 and to the latch box 32, the purpose of this chain is to limit the pivotal movement of the yoke member 31 when moved to an open position where the same may be hooked over a pin 4-1 to prevent opening of the yoke, when it is desired to keep the same closed, while the remainder of the yokes are being opened. It is, of course, understood that a plurality of these yokes are placed in alignment one to each 9 stall.

The manner of operating my device is as follows Assuming that the parts are in the position shown in full lines in Figure 1, and it is desired to open all of the yokes, the lever 21 is actuated so as to move the cable 17 in the direction of the arrow in Figure 1. This pulls upon the pin 18 causing the longitudinal members 14 to slide toward the right of the drawing. This action moves the latch block 13 toward the right of the drawing and as the bolt 33 is in engagement therewith, the same is carried in the same direction. When it is desired to close all of the yokes, the lever 21 is moved in the opposite direction causing the cable 11 to move in the direction of the arrow of Figure 1, thus pulling upon the pin 12 and causing the longitudinal members ll to move toward the left of the drawing, thus closing all of the yokes. Should the operator desire to pre vent the opening of one of the yokes, the chain will be hooked upon the pin 41, with a result that movement of the latch block will merely cause the bolt to move clownwardly within its boX against the tension of the spring 34:, due to the fact that the bolt is provided with a chamtered end.

When it is desired, one stall may be released independent oif the others by pushing downwardly on the operating pin 36 which will withdraw the bolt and allow the single stall to be opened.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement otparts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim w 1. In a device of the character described, a horizontal pipe, longitudinal members movable in said pipe, a block positioned on said longitudinal members, a yoke positioned beneath said pipe, a bolt carried by one portion of said yoke and adapted to'engage said block within said pipe, for the purpose specified.

2. In a device of the character described, a pipe, longitudinal slidable members positioned Within said pipe, a latch block secured to said longitudinal members, a pivoted yoke positioned beneath said pipe, a bolt secured to one portion of said yoke and adapted to engage said latch block, remotely controlled means for moving said longitudinal members laterally, for the purpose specified.

3. In a device of the character described, a pipe, longitudinal slidable members positioned within said pipe, a latch block secured to said longitudinal members, a pivoted yoke positioned beneath said pipe, a bolt secured to one portion of said yoke and adapted to engage said latch block, remotely controlled means for moving said longitudinal members laterally, a pin positioned in said latch block, a pair of sheaves mounted on said pipe, a cable reaved over said sheaves, and having one end of said cable secured to said pin for the purpose of moving said pin in one direction, a second pin positioned in said latch block at a point remotely located from said first mentioned pin, the opposite end of said cable being attached to said second mentioned pin for the purpose of moving said pin in the opposite direction from said first mentioned pin, for the purpose specified.

In testimony whereof I afiix my signature.

MARTIN ANDERSON.
